代词的用法和概念是什么

  代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。下面是小编给大家整理的代词的用法和概念简介,希望能帮到大家!

  代词的用法

  1)人称代词的主格在句子中作主语或主语补语,例如:

  John waited a while but eventually he went home.

  约翰等了一会儿,最后他回家了。

  John hoped the passenger would be Mary and indeed it was she.

  约翰希望那位乘客是玛丽,还真是她。

  说明:在复合句中,如果主句和从句主语相同,代词主语要用在从句中,名词主语用在主句中,例如:

  When he arrived, John went straight to the bank.

  约翰一到就直接去银行了。

  2)人称代词的宾格在句子中作宾语或介词宾语,但在口语中也能作主语补语,第一人称在省略句中,还可以作主语,例如:

  I saw her with them, at least, I thought it was her.

  我看到她和他们在一起,至少我认为是她。(her做宾 语,them做介词宾语,her做主语补语)

  a. -- Who broke the& nbsp;vase? --谁打碎了花瓶?

  b. -- Me. --我。(me做主语补语= It’s me.)

  说明:在上面两例句中,her和me分别作主语补语。现代英语中多用宾格,在正式文体中这里应为she和I。

  3.2 人称代词之主、宾格的替换

  1) 宾格代替主格

  a.在简短对话中,当人称代词单独使用或在not 后,多用宾语。

  ---- I like English. --我喜欢英语。

  ---- Me too. --我也喜欢。

  ---- Have more wine? --再来点酒喝吗?

  ---- Not me. --我可不要了。

  b.在表示比较的非正式的文体中,常用宾格代替主格。 但如果比较状语的谓语保留,则主语只能用主格。

  He is taller than I/me.

  He is taller than I am.

  2) 主格代替宾格

  a. 在介词but,except 后,有时可用主格代替宾格。

  b. 在电话用语中常用主格。

  ---- I wish to speak to Mary. --我想和玛丽通话。

  ---- This is she. --我就是玛丽。

  注意:在动词be 或to be 后的人称代词视其前面的名词或代词而定。

  I thought it was she. 我以为是她。 (主格----主格)

  I thought it to be her. (宾格----宾格)

  I was taken to be she. 我被当成了她。 (主格----主格)

  They took me to be her. 他们把我当成了她。 (宾格----宾格)

  代词的概念

  代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。英语中的代词,按其意义、特征及在句中的`作用分为:人称代词、物主代词、指示代词、自身代词、相互代词、疑问代词、关系代词和不定代词八种。

  物主代词

  1)物主代词既有表示所属的作用又有指代作用,例如:

  John had cut his finger; apparently there was a broken glass on his desk.

  约翰割破了手指,显而易见,他桌子上有个破玻璃杯。

  物主代词有形容词性(my, your等)和名词性(mine, yours等)两种,形容词性的物主代词属于限定词。

  名词性的物主代词在用法上相当于省略了中心名词的 --’s属格结构,例如:

  Jack’s cap 意为 The cap is Jack’s.

  His cap 意为 The cap is his.

  2) 名词性物主代词的句法功能

  a. 作主语,例如:

  May I use your pen? Yours works better.

  我可以用一用你的钢笔吗? 你的比我的好用。

  b. 作宾语,例如:

  I love my motherland as much as you love& nbsp;yours.

  我爱我的祖国就像你爱你的祖国一样深。

  c. 作介词宾语,例如:

  Your should interpret what I said in my sense of the word, not in yours.

  你应当按我所用的词义去解释我说的话,而不能按你自己的意义去解释。

  d. 作主语补语,例如:

  The life I have is yours. It’s yours. It’s yours. 我的生命属于你,属于你,属于你。

  不定代词

  一、不定代词定语从句用法

  在限制性定语从句中,当先行词指人时,关系词可用who(作宾语是还可用whom)或that,二者常可互换.

  但在下列情况中,用who(m),而不用that:

  (1) 当先行词是one,ones,any,few,anyone,anybody,someone,somebody,everyone,

  everybody等词时.如:

  Is there anyone who can answer this question?

  He was among the few who managed to live through the enemy prison camp.

  注:在非正式文体中可以说:You’re the one that knows where to go.)

  (2) 当先行词是he,they,those,people,person等词时.如:

  He who wants to catch fish just not mind getting wet.

  Those who are against the proposal put up your hands.

  注:在固定结构的谚语或习语中,可用he that….如:

  He that promises too much means nothing.

  (3) 当先行词有较长的后置定语修饰时.如:

  Do you know the writer in blue with thick glasses who is speaking at the meeting?

  (4) 在分隔式定语从句中,若先行词指人,为了明确修饰关系,应当用who(m).如:

  A new master will came tomorrow who will teach you German.

  There’s only one student in the school who/whom I wanted to see.

  I was the only person in my office who was invited.

  (5) 两个定语从句同时修饰一个指人的先行词,第二个定语从句常用who(m)来引导,如:

  She is the only girl I know who can play the guitar.

  二、定语从句用法归纳

  定语从句由关系代词who、whom、whose、which、what、as和关系副词where、when、why等引导,但须记住:

  1.what不能引导定语从句.

  2.关系词的分析须考虑它在定语从句中的成分。

  一.指人的关系代词有who、whose、whom、that. 试分析:

  The old man who/whom /that we visited yesterday is a famous artist.

  Miss Wang is taking care of the child whose parents have gone to Beijing .

  The man with whom my father shook hands just now is our headmaster. (=The man who/whom that my father shook hands with just now is our headmaster.)注:

  A. 指人时有时只用who不宜用that。

  1.先行词为one、ones或anyone

  (1)The comrade I want to learn from is the one who studies hard and works hard.

  (2)Anyone who breaks the law should be punished.

  2.先行词为these时

  These who are going to Beijing are the best students of our school.

  3.在there be 开头的句子中

  There is a student who wants to see you.

  4.一个句子中带有两个定语从句,其中一个定语从句的关系代词是that,另一个宜用who,以免重复。

  The student that won the first prize is the monitor who works hards.

  5.在非限制性定语从句中

  A。I met a friend of mine in the street, who had just come from Japan.

  B.主句以who开头的句子中,只用that,不用who。

  二.指物的关系代词有which、whose(=of which)、that. 试分析:

  1. I like the books which / that were written by Lu Xun.

  2. The desks (which/that) we made last year were very good.

  3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)

  4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)

  注:

  A. 介词如果位于作为其宾语的关系代词之前时,只能用whom、 which不能用who或that.

  (1). The girl about whom they were talking is our monitor.

  (2). The book in which there are many interesting things was written by Li Ming.

  B. 部分短语动词中的介词不可与动词拆开,在定语从句中其介词不可前置,只能放在其动词之后。

  Is this the book which she is looking for?

  The old man who/whom they are waiting for is Professor Li.

  The child who/whom she is looking after is Wang Ping’s son.

  C. 指物时,下列情况下只能用that ,不宜用which。

  (1)先行词为不定代词,如All、much、anything、everything、nothing、something、none、the one等。

  We are willing to do anything that is good to the people.

  I have told them all (that) I know.

  All that can be done has been done.

  (2)先行词是序数词或被序数词、修饰时。

  The first book that I read last night was an English novel.

  (3)先行词是形容词最高级或被最高级修饰时。

  This is one of the most interesting films that I have ever seen.

  This is the best that can be done now.

  (4)如果有两个或两个以上分别表示人和物的先行词时(先行词既有人又有物),定语从句的关系代词用which和who都不合适,只能用that。

  We know nothing about the doctors and the hospitals that you are talking about.

  There are sheep and men that can be seen on the hill.

  (5)如果先行词被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修饰时。

  This is the only book that can be lent to you.

  (6)当主句是以which开头的特殊问句时,关系代词只用that。

  Which is the dictionary that he used yesterday ?

  D.只物时,下列情况下只能用which,不宜用that。

  (1)关系代词放在介词之后

  This is the factory in which we once worked.

  (2)非限制性定语从句中

  This is the book, which is written by Lu Xun.

  (3)that,Those作主语时

  Those which are on the desk are English books.

  E.先行词前有such、the same、 as时, 关系代词用as,不用that, 但the same…as…表示同样的, the same…that…表示同一的

  He knows as many people as are present at the meeting.

  Such people as you refer to are rare nowadays.

  三.比较When/which、where /which、why.

  which I still never forget.

  This is the day when I joined the party.

  which he spent reading the books.

  where I found the book.

  which makes machines.

  This is the place which we once visited.

  which I will never forget.

  which I am looking for.

  限制性定语从句与非限制性定语从句的区别:

  限制性定语从句

  非限制性定语从句

  All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了,不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了,他们学习努力。(没有人不及格,这些学生都很努力。)

  从句是先行词不可缺少的定语(如去掉,主句意思就不完整或不正确。) 从句是对先行词的附加说明(如去掉,主句意思仍清楚,不受影响。) 与主句关系密切,不用逗号 与主句关系不十分密切,用逗号与主句隔开译为汉语时,从句译在先行词前,与先行词用“的”连接 译为汉语时,从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略 关系代词不能省略关系代词as和which

  先研究下面两个例句:

  ○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来,这头象像条蛇。

  ○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格,这使得他父亲很生气。

  这两个例句中,as和which所代表的都是整个主句所表示的内容。但有两点不同之处:

  1. 在形式上as引导的非限制性定语从句可位于主句的后面,也可位于主句的前面;而which引导的非限制性定语从句只能位于主句的后面,不能位于主句的前面。

  2. 在意义上,as引导的定语从句和主句的关系一般为一致关系,常译为“正如……”,“就像……”,而which引导的定语从句和主句的关系是因果关系,或which引导的定语从句是对主句的评论。因此,在意思通顺的情况下,which可代替as,而as许多时候不能代替which,如句○2。再如:

  1.He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料,他又迟到了。/他又迟到了这是我们早就料到的。

  2. The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了,因此整条街很脏。(不用as)

  3.The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财,这是不光彩的。(不 用as)

  4.He takes exercise everyday, which has done a lot of good to his health. 他每天运动,这对他的身体很有好处。(不用as)

  5.As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样,英语对于初学者说,是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如:

  1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。

  =Books such as this are …

  =Books like this are …

  2.I live in the same building as he (does). 我和他住再同一座大楼里。

  3.He knows as many people as are present at the meeting. 他认识所有到会的人。

  4.That day we all got up early as usual. 那天我们和平时一样,都起得很早。

  “One of the +复数名词”后面定语从句中谓语单复数情况

  这一结构后面的定语从句的谓语动词通常用复数形式,跟定语从句所*近的那个复数名词在数上保持一致。如:

  1. That is one of the books that are required for study at school.

  2. This is one of the most wonderful novels that have been published since 1990.

  3. She is one of the few persons who know Spanish .

  4. This is one of the most famous plays that were written in the thirties,

  如果one of +复数名词这一结构前面带有the only、the very之类的限定语,后面定语从句的谓语动词则要用单数形式,这是因为定语从句在意义上修饰的是而不是那个复数名词。如:

  1.He is the only one of the teachers who knows French in our school.( 修饰the only one)

  He is one of the teachers who know French in our school.( 修饰the teachers)

  2.This is the only one of the rooms that is free now. (修饰the only one)

  This is one of the rooms that are free now. (修饰rooms)

  as与which引导的定语从句

  两者均可引导非限制性定语从句,有时可以互换,但下列情况多用as。

  1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.

  2. 当与such或the same连用时,一般用as。 Such books as you tell me are interesting. I have the same plan as you.

  3. 当从句和主句语义一致时,用as,反之则用which。 She has married again, as was expected. She has married again, which was unexpected.

  4. as在从句中作主语时,后面常接行为动词的被动语态,如be known,be said,be reported等,如从句中行为动词是主动语态,一般要用which作主语。

  She has been late again, as was expected.

  Tom has made great progress, which made us happy.
